**BUG** Concise problem statement: Tried on two different Widows 10 PCs with Chrome browser. When editing a schematic, when I click on the "PARTS" icon at left, a parts list window opens. If I try to resize the window, I can only make it smaller. That would be OK, but once I attempt to resize by clicking on the window edge and getting a double-arrow (for resizing windows), I cannot get OUT of that mode (with with either right click or ESC) so any mouse motion only serves to reduce the window. Window resizing is only one direction, down, so I cannot even undo accidental window reductions. I have to completely exit EasyEDA and start over and make sure I don't touch the PARTS window edge to use the PARTS list. Steps to reproduce bug: 1. IN schematic edit mode, open PARTS window 2. Try to resize parts widow and make it larger 3. Results: Parts window can then ONLY be reduced and program will not leave window resize mode Expected results: Ability to increase or decrease PARTS window size and exit resize mode with right click or ESC Browser: Chrome
